To 'LZ'Z whom it may concern,.-

Beit known that LIsoM RUrUs CHoAnacitzen of the United States, residing at Strawn, in

enable others skilled in the art to which it ap pertains to make and use the same.

This invention relates to baling-presses, and particularly to presses of that character employing a beam or sweep for actuating the plunger-operating mechanism.

The object of the invention is to provide power mechanism for baling-presses of the stated type which is simple and inexpensive of construction and is adapted to gradually increase the applied power as the resistance to the compression of the material increases, while at the same time preventing the resisting strain from falling upon the draft-animals. It is well known that in the ordinary construction of presses of this character most of the resisting strain is sustainedl directly by the beam or sweep and falls upon the draft-animals and that as the compressing-plunger nears the limit of its working movement the resisting strain reaches the maximum, making the work very hard upon the animals at -a certain portion of the path of revolution of the beam or sweep. By my construction this strain is to a large extent relieved from the draft-animals and transferred to the frame of the power mechanism, making the work easier upon the animals, and at the same time the power applied gradually increases with the resistance to the compression of the material, whereby tightly-compressed bales may be formed.

In the accompanying drawings, Figure 1 is a top plan view of a baling-press embodying my invention, showing the position of the parts when the plunger is retracted., .Fig. Zisa? similar view showing the position of the parts when the plunger nears the limit of its compression stroke, the compression-chamber appearingin horizontal section. Fig. 3 is a side elevation of the power mechanism and a vertical longitudinal section through the balingchamber. Fig. 4 isa cross-section on line 44 of Fig. 1. Y Fig. 5 is a detail view of the driving-bar of the beam or sweep. Fig. 6 is a detail view of the plunger-bar. Fig. 7 is a detail cross-section on line 7 7 of Fig.` Y3. Referring now more particularlyto the drawings, the numeral .1 represents the balingchamber of the press,`whi ch is provided at its rear end with a hopper 2 for the feed ofthe material thereto and which may be of any approved construction. In the present instance I have shown the balin U-chamber as being provided with a yielding portion 3 at its top, which is adapted to clamp the follower-blocks 4 in position in the usual manner and whose outer free end is pressed downward by a pressureblock 5, yieldingly retained in clamping posi.- tion by a bow-spring 6, whose ends bear upon an adjustable bar 7, carried by tie-bolts 8, which are provided with adjusting-nuts 9, whereby the bar may be adjusted to apply greater or less pressure to said pressure-block. The plunger 10 'is mounted to reciprocate in the baling-chamber and is provided withaJ cut-olf table `or apron 11, which closes the hopper and prevents inlet of feed to tliebaling-chamber when the 'plunger on its compression stroke moves past said hopper. Spring pawls or detents 12 are applied to the sides of the baling-chamber and are so constructed as to allow the plunger to have free movement, while preventing the rebounding of the hay or material to be compressed, as will be readily understood by those versed in theart. y if.

The mode of operation of baling-presses of this typenemploying reciprocating plungers and follower-blocks being well known, any further explanation in reference thereto is deemed unnecessary, and I will therefore now proceed to describe the power mechanism in which my invention chiefly resides.

Disposed in rear of the baling-chamber isa power-frame 13, which is adaptedA to rest horizontally upon the ground or, upon suitable supporting-wheels and which is providedwith a forwardly extending tongue 14, having knuckles 15 at its forwarderrd'gthrouglrrwhich I and ,coacting knuckles 16 is pa'sse'da pin or'v bolt 17 ,serving the function of a pintle in IHC pivotallyconnecting the power-frame to the rear of the baling-chamber, so as to allow one to have free movement relatively to the other when the parts are mounted upon supporting-wheels and are being transported from place to place and also to allow the frame to be applied to or detached from the balingchamber at will. Vhere the baling-press is to be stationary, the balingchamber and power-frame may rest upon the ground or a suitable fixed foundation; but if it is desired to make the press transportable the balingchamber and power-frame may, as above stated, be mounted upon supporting-wheels. In such case I may dispense with the ,described connections 15, 16, and 17 and connect the tongue 17 with an axle on rear end of the baling-chamber, the axle being mounted in any well-known manner to allow the main parts of the apparatus to have relative movement and be readily steered and guided. lt will be observed that the tongue 14 projects from one side of the frame 13, which lies mainly to one side of the central line of the baling-chamber 1, and mounted upon the frame in line with this tongue is a pivot pin or bolt 18, reinforced by a brace 19. The plunger is connected to a reciprocating plunger bar or rod 20, which is provided at its rear or free end with straps 2l, secured to the top and bottom of the same and projecting beyond the end thereof and having L-shaped ends 22. The link or toggle-lever 23 is pivotally mounted at one end upon the pivot-pin or post 1S and at its other end is disposed between the outer ends of the straps 21 and is connected thereto by a pivot 24. An operating-lever 25 is pivoted between the lateral extensions of the L-shaped ends 22 of the straps by a similar pivot-pin 26 and is cut away on one side between its center and outer free end to form a contacting portion or shoulder 27, the reduced portion of the operatinglever formed by the cut away of the same providing an arm 28, which performs a function hereinafter described. The lever 25, being pivoted only at its inner end by the pin 26 to the plunger rod or bar 20, is free to swing and reciprocate and is held from rearward movement beyond a predetermined point by a stop 29, fixed upon the frame 13. On the outer side of the frame 13 and adjacent to the forward end thereof a pivot-bolt 30 is disposed, and on this bolt a beam or sweep 3l is mounted to turn or rotate in a circular path and may be provided at its free end with any approved kind of draft appliance 32 for the attachment thereto of draftanimals. Bolted to a pivoted end of the beam or sweep is an operating-bar 33,having curved ends 34, which are adapted to alternately engage the shoulder 27 of the lever 25 at each half-revolution of the beam or sweep to operate said lever to communicate motion to the plunger-bar 20 to force the plungeron its compression stroke. Of course the beam orsweep 21 may be directly provided with contacting portions having the functional qualifications of the portions 34, if so desired.

By reference to Fig. 1 of the drawings, in which the plunger is shown as being at the the levers 23 and 25 project outwardly and rearwardly in reverse direction and at an oblique angle to the bar or rod 2O with the said lever 25, disposed in contact with or in j uxtaposition to the stop 29. By a comparison between this igure and Fig. 2 it will be seen that as the beam or sweep 3l is turned or rotated in the direction of the arrow one of the contacting portions 34 of the bar 33 will engage the shoulder 27 of the lever 25 and swing said lever inwardly and diagonally across the frame 13, thus moving the bar 20 and lever 23 against tension of the spring 35 inwardly until they straighten out or come in line, and thus communicate forward movement to the plunger. The plunger nears the limit of its forward or compression stroke as the bar 2O and lever 23 begin to come in line and reaches the limit of such movement kwhen said bar and lever come in direct alinement, and the lever 25 extends at right angles thereto across the frame 13 and the arm 28 abuts against one side 'of the bar 33 and holds the lever 25 in alinement with said bar. Then as the sweep continues to move the curved shoulder 34 of the bar 33 moves out of engagement with the shoulder 27 of the lever 25, and the bar engages the arm 28 and swings the parts out of locking engagement, whereupon the power mechanism is retracted to the position shown in Fig. 1 by the spring 35. As the sweep then continues to rotate the other curved end 34 of the bar 33 will engage the shoulder 27 of the lever 25 and operate the plunger in like manner, thus reciprocating the plunger twice on each rotation of the sweep.

As a result of the construction and mode of operation of the parts as above described it will be apparent that when the operation of moving the plunger forward begins the strain resulting from the resistance of the material to compression will fall upon the pivot 30; but as the sweep continues to rotate and the bar 2O and lever 23 are being brought into alinement the resisting strain which gradually increases as the plunger moves forward will be transferred to the pivot 1S and will be sustained by said pivot and the frame 13, thus allowing all of the applied power to be employed for bringing the bar 2O and lever 23 into alinement and relievingthe draf t-animals of the additional labor which would otherwise fall upon them of sustaining the strain and at the same time applying power to operate the elements of the power mechanism. Further, it will be seen that the bar 20 and lever 23 constitute, in effect, a pair of toggle-levers, whereby the power applied gradually increases proportionate to the resistance of the material under compression, and that as the plunger nears the limit of its compression stroke hy straight IOC IZO

ening out of the parts 2O and 22 into longitu-V dinal alinement and the throwing of the resisting strain on the pivot I8 that portion of the work of the draft-animals ordinarily required to take up the strain is utilized as additional power for operating the plunger, thus enabling the material to be compressed tightly or to a denser condition. Thus the work of the! draft-animals is rendered easier and a more efficient compressing action is obtained.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the. invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or'sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
